I was worried initially, as the availability at T-48 was J0. I waited a couple of hours, checked EF, and found that it was now J2, so went ahead and cancelled/reacquired the upgrade (switching eUpgrade to complimentary upgrade).
Has anyone tried this when the flight shows J0?
I have done it at J0. It may be risky. I opened 2 windows, one on each of 2 bowsers. I cancelled the flight from my wallet (I don't call in to do this), then immediately rebooked it and upgraded it, without problems. The biggest concern is that Y is available, so that you can rebook and that is why I open 2 windows. I start to book the flight on one of the windows, and then complete it once I cancel the other.
